摘要： There is provided a method for evaluating prestressing force of a bonded tendon. The method includes: striking a prestressing strand of a bonded tendon with an impact hammer; measuring an acceleration response signal from the prestressing strand using an accelerometer, and receiving the acceleration response signal with a data logger; and calculating stress wave velocity based on the acceleration response signal received by the data logger, and evaluating prestressing force of the bonded tendon, based on the calculated stress wave velocity, using a controller.
